CONCRETE WALL AND IVIETHOD OF MAKING- SAME.

Application filed March 2, 1920. Serial No. 362,881.

T 0 all whom it may concern:

Be it known that I, LYMAN B. LANGWOR-' THY, a citizen of the United States of America,-and a resident of Chicago, county of Cook, and State of Illinois,'have invented certain new and useful Improvements in Concrete \Vall and Methods ofillaking Same, of which the following is a specification.

This invention relates mainly to the construction of foundations, walls, caissons, dikes, jetties, breakwaters, and the like, es pecially where great strength and safe foundations are required. The main objects of the invention are to provide an improved form of piles, wall units or sections adapted for sinking into place in the manner of piles; to make provision therein for applying a hydraulic earth removing jet; to provide a reinforced concrete pile of improved form adapted for ready sinking; and to provide for injecting through the several piles material to form a concrete footing for the wall after the piles are in place.

An illustrative embodiment of this invention is shown in the accompanying drawings, in which Fig. 1 is a front'elevation of a reinforced concrete wall composed of similar internal jetty piles, one of the piles being in section to show the reinforcing.

Fig. 2 shows an edgewise view of said wall at one of the joints where adjacent piles abut. I

Fig. 3 is a section at 3-3 on Fig. 1.

Fig. at is a front elevation of awall composed of alternately disposed piles and panels.

Fig. 5 is a section at 5-'5 on Fig! 4 where adjacent piles abut.

Fig. 6 is similar to Fig. 5 except that the panel is guided on both front and back by pile flanges.

Fig. 7 is an enlarged vertical sectional detail of the spud and associated parts on the line 7-7 of Figure l.

In the construction shown in the draw-- ings, reference being had to Figs. 4 and 5, the wall units 1 and 2 are all of reinforced concrete and each is provided with one or more water tubes or jet pipes 3. Said tubes 3 are arranged lengthwise of the piles l and panels 2 and project at the ends as at r and Water may be supplied thereto under pressure as by connecting same at 4.

As thus used, the water is forcibly ejected at the lower ends '5 whereby the earth is hydraulically loosened and more or less removed from the path of the downwardly moving part. Thus the body 1 or 2 may be readily sunk into place.

The piles l are provided with flanges or rabbets 6 on their front corners to secure the interposed panels 2 against the pressure of the material held back by the wall. Rear flanges 6" stances. a

The abutting edges of the wall members are longitudinally grooved in mutual registry nearly to the lower ends to provide a closed tubular chamber or cup 7 to receive a locking key of bonding material 8, the botk tom of said cup being indicated at 7 means 9, and each panel 2 contains a reinforcement 10. The edges of reinforcements 9 and 10 project somewhat into the corresponding cup grooves 11 and 12 respectively, to engage with or become set in the body of the key 8, as explained in my copendingapplication Serial No. 362,882, filed of even date herewith. Each wall. member or unit 1 and 2 is provided with a lifting staple 13 or the like set in its in Figs. 1, 2 and 4.

In case the wall is tobe constructed of piles alone, as shown in Figs. 1 and 3, the pilesl i may be formed substantially as in Fig. 4 except that omitted. The reinforcement 15 may also be of a different design, but the edges thereof extend into the' cups 16"substantially as in the first described form of wall. A footing 8 is forced down under the wall through the jet pipes 3 and apertures 11 and l2after the piles and'panels are in place.

are also desirable in some iu-- Each pile 1 is provided with reinforcing:

upper end, as shown the guide flanges are In each case, the tubing for the jet pipes tioned and related to the staple 13 as to be. protected thereby from mechanical in ury.

The lower ends of spuds 17 and tubes 3 are about flush. though thejet pipe mayproject somewhat beyond the spud. The lower end of each pile is protected by a metal shoe
